|An all-powerful brute, Juggernaut is the half brother of Xavier. When he became too strong and too vengeful to live amongst normal people, Xavier had him detained in a maximum security prison which held him underwater and left him in a state of permanent sleep.
Mystique freed him in hopes of getting him to steal Cerebro from Xavier but he was defeated by a combined effort by The X-Men and The Brotherhood.
He was once again freed by Mystique and she placed Xavier in his containment tank. After creating havoc in Michigan, he was stopped by The X-Men. He managed to escape being captured and was never heard from again.
